The plastic closure consists of a rotating cap (1) with a sectoral pouring hole and with a slide (2) guided on its under side in such a way as to be capable of being displaced in a translational manner in relation to the pouring hole. The slide exhibits a downward-projecting cam on its under side. Lying beneath the slide (2) is a gate cap (3). Also present in its cover (6) is a sectoral pouring hole and behind it additionally a groove as a gate guide for the cam on the slide (2). The gate cap (3) is installed in a stationary manner on a bottle neck or a container spout. If the rotating cap (1) is caused to rotate relative to the gate cap (3), the cam of the slide will be guided along the gate guide and will pull the slide (2) into the open position, whereas rotation in the opposite direction will cause the slide (2) to be displaced back into the closed position. |
